Gamete Rescues from Gonads of Wild Animal Post-mortem

Wild animals usually die unexpectedly. After post-mortem, there is a short time for gamete rescue because tissue degeneration occurs rapidly in the field area. It is crucial to develop rescue strategies to obtain good gamete quality for future offspring production. Applications of reproductive biotechnologies, e.g. gamete cryopreservation, in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), in vitro follicular culture and xenotransplantation, are necessary to propagate the value rescued genes to the endangered populations. Epididymis and testis are sources of male gametes while oocytes from antraland preantral follicles are female gametes that have been reported to successfully produce offspring. This review contains summary of the current research interests that aim to rescue, preserve and apply valuable gametes from wild endangered animals after death.
